study to evaluate the efficacy and safety of benralizumab in adult patients with mild to moderate persistent asthma

Conditions: Asthma

Summary: the purpose of this trial is to confirm the safety and clinical benefit of benralizumab administration in asthma patients with mild to moderate persistent asthma in order to gain an understanding of the benefit/risk of benralizumab across the spectrum of asthma disease.


Eligibility criteria:
